Some time back I managed to get an Apexi Power FC ECU and commander.

Now I have read that you need to change three wires, Camshaft position sensor, crankshaft position sensor and fuel pump relay wires.

I have swapped the cam and crank sensor wires over but havent done the fuel pump relay. The car starts and runs perfectly. Do I need to do anything with the 3rd wire ( fuel pump). It may appear to be a daft question as the car runs but I thought i would ask it for piece of mind.

Thanks

Fuel pump wire only needs swapping on 97/98 due to the standard ECU having an inbuilt immobiliser.

The MY99/00 has an external immobiliser, so you are fine.

Confirmed my thoughts.

Many Thanks

My friend is in the middle of installing his PFC (MY98 WRX), cam and crank wires are now swapped, so what needs to be done to the fuel pump wire? Apparently the immobiliser is preventing the car from starting (fuel pump is dead), but exactly what should be done to the fule pump wire(s), and where?

Thanks !

Doing a bit of research... on connector 137, change pin 17 to 7, is that it?

Yes..

Daz,

just be careful as the standard map is way too agresive on the UK 99~00 engine..
